AUXILIARY APPARATUS FOR CONDENSERS.

Application filed April 18, 1922 Serial No. 554,512.

Top whom it may concern:

Be it-known that I, ROBERT same, a citizen otthe United States,,residing in the city and county of Philadelphia, State of Pennsylvania,have invented certain neW i and useful Improvements in AuxiliaryApparatus tor-Condensers, of which the foll'ovvingfis a specification.My invention relates to apparatus for removing from a vessel,particularly one in which there is to be produced or maintained avacuum, as a condenser or evaporator, elastic fluid, as air or gas, andliquid, as condensate or Water, by separate ejectors which discharge theair or gas and condensate orliqruid, respectively, through different orindependent paths, to higher pressure or otherwise.-

My invention resides in apparatus of the character hereinafter describedand claimed. For an illustration of one of the various forms myinvention may take, reference may be had to the accompanying drawing,

,WlllCll is avertical sectional vieW through a portion of the condenserand associated apparatus for removing air and condensate.

Reter-ring' to the drawing, C represents the shell, of a condenser, forexample, the shell of a surface condenser or a marine condenser such asused upon board ship to condense the exhaust steam from the engines orturbines. Both air and condensate are ivithdrawn through the outlet 0.The condensate collects in the hot Well or other receptacle H, the levelof the Water or con-- den'sate being indicated at W. In the condensateis submerged an ejector comprising the nozzle N aligned With thecombining cone or guide tube B, which in turn is aligned with thediffuser or other tube D communicating with the suction chamber S, ofany suitable type, of pump P, which is indicated: as and preferably is areciprocating Wet air pump. Through the pipe A,

7 controlled the valve -there is delivered undersuitable pressure to thenozzle N any suitable motive fluid, as'elastic motive fluid, as steam,or liquid, as Water. The motive fluidolelivered through the nozzle Ncauses the liquid or ,condensate to be drawn into themember Bi and to bedelivered to the tube or difli'user D and discharged therefrom into thesuction chamber S at higher pressure than obtains in the hot ell H.

The leaving the conde'nser'C through the openlng 0 passes upwardly tothe ejector Whose nozzle structure is indicated at M and having thediffuser or equivalent D Me,- i

tive fluid of any suitable character, preferably steam of suitablepressure, is delivered by the pipe E, controlled by the valve an,

to the nozzle structure M, which delivers fa j etot' motive fluid whichentrains the air, the

mixture being delivered to the ditfuserD at high veloclty. The velocityof the mixture decreases and is converted into pressure in the diffuserD and the mixture of steam and air is delivered either directly to thesuction chamber S, or preferably, as in dicatechto a condenser 0 ,111Which the motivecfiuid steam is more or less completely condensed, thecondensate from the condenser C and the air passing onward to thesuction chamber S, from Which the con- Vdensate, from both condensersand the air from the condenser C is removed by the pump P The ejectorsdeliver, respectively, the air and condensate or other liquid against orto I substantially the same pressure, to Wit, that existing n thesuction chamber S. The pressures of both the air and the liquid orconden'sateare increased by the ejector's to a substantially equal orcommon pressure, the air and condensate being then removed "by the pumpP upon Which the load ,is correspondingly less because of thepreliminary compression ofthe air and increase in pres- A sure of theliquid orconde'nsate. The-ejectors in effect assist the pump P bypreliininarily raising the pressure of the air and liquid or condensate.

While the ejectors herein disclosed are ot simple single noz'zlef types,it Will beunderstood that any suitable forms of ejector may be used, asfor example, those employing a plurality of steam nozzle's, or ejectorshaving posed outside of and s'urroundsthe annular nozzle whichdischarges radially into the diffuser. The apparatus closed in LettersPatent of the United States No. 1,3&2,4t71, granted me JuneYS, 1920. v ai What I claim is z y 1. The combinationwith a annular nozzles anddiffusers, or ejectorsofi; the latter type in which the diffuser 1sdisherein disclosed is disreceptacle for liquid, of an ejectorsubmergedin the liquid, a second receptacle to which said liquid is delivered bysaid ejector at higher pressure, and 'a-se'cond ejector delivering fluidat increased pressure to said second receptacle inindependently of saidfirst named ejector.

2. The combination with a receptacle for liquid, of an ejector submergedin the liquid, a second receptacle to which said liquid is delivered bysaid ejector at higher pressure, and asecpnd ejector delivering air atincreased pressure to said second receptacle independently of said firstnamed ejector.

3. The combination with a receptacle for liquid, of an ejector submergedin the liquid, a second receptacle to which said liquid is deliveredby'said ejector at higher pressure. 'a. second ejector delivering air atincreased pressure to said second receptacle independently of said firstnamed ejector, and means for withdrawing the air and liquid. from saidsecond receptacle and raising them to higher pressure.

4. The combination with a receptacle, of a steam-operated ejectordischarging air at higher pressure, a condenser into which the ejectordischarge is delivered and in which the steam is condensed, thecondensate and air delivered into said receptacle, and a second ejectordelivering liquid from lower pressure into said receptacle.
